Obviously it will be larger and heavier than new bikes, but I competed on one in the late 80's and did fine against new bikes of the day. One major difference between the 242 and newer bikes is the cable clutch. Going from cable to hydraulic can be a little weird. Threre are parts, but it can be a little more difficult than a new bike. If you are familiar with trials bikes though, you are already used to this. Hope this helps.

This is a easy answer NO unless you want to compete in Vintage events.

Engine parts for this model were difficult to get for the 242. My friend in Pa. was happy to get the last known new piston for his bike a few years ago at Mid Ohio swapmeet. Maybe things are better now? My understanding other model Montesa trials bikes have a better supply of parts.

If you compete in Vintage trials I believe the 242 is a GREAT bike, sort of a interim from old slow rev ving heavy bikes and has snappier power and lighter weight.

I bought one two years ago for use on my own property to play with. My first trials bike and I had thoughts of doing novice/vintage trials with it, but I just haven't had time to practice. It's a nice bike and truly stock/original. For parts try http:///www.southwestmontesa.com/index.html
I got a complete parts manual from them but it is in Spanish. If you do it, let me know.

For any of you Montesa 242 riders, I have been cleaning up the garage lately and came across an engine I took in trade with some other spanish bike parts. The engine number begins with 39M, which I believe makes it a 242. It is coomplete, in good condition, turns over smooth, etc...with electrics. I believe I have a swing arm for this one as well.

So you did not give us a real reason for wanting the Montessa 242. Do you just want to play around with a trials bike on your property? Do you want to compete in vintage trials? Do you think it would compete in modern trials?

It would be fun to just play on.

It is a competitive vintage bike with the right equipment on it.

It is not the bike you want to be on to go up against today's bikes and courses. It was made in the "NO STOP" era and trials is much different today. Take these things into consideration.

GREAT BIKE 4 a newbe SCOTT HEAD won at least 1 national Championship aboard won of these.........I believe it was 84 my first experience with National trials.
